Turn On/Off cars Light

Options
Hi everyone, I need help to understand something.
In my room, everyone instances their car, the car has lights attached to it. When I activate / deactivate the lights, this only works for the owner of the car.
I tried to make a PUNRPC call, where I get the viewID of the player. But I can't get the lights to come on.
Can anyone show me a way?
I thank.

My Code:
public void AccendiSpengifari()
    {
        if (FAD.isActiveAndEnabled)
        {
            FAD.gameObject.SetActive(false);
            FAS.gameObject.SetActive(false);
            FPD.gameObject.SetActive(false);
            FPS.gameObject.SetActive(false);
            MostraIFariAccesi();
        }
        else
        {
            FAD.gameObject.SetActive(true);
            FAS.gameObject.SetActive(true);
            FPD.gameObject.SetActive(true);
            FPS.gameObject.SetActive(true);
            MostraIFariSpenti();
        }
    }


    void MostraIFariAccesi()
    {
        photonView.RPC("AccendiFari", RpcTarget.All, photonView.ViewID);
    }

    [PunRPC]
    void AccendiFari(int playerViewID)
    {
        //Debug.Log(playerViewID.ToString());
        GameObject zzzplayer = PhotonView.Find(playerViewID).gameObject;
        Debug.Log(zzzplayer.name + " Ha acceso i fari, player viewID: " + playerViewID);
        //zzzplayer.transform.FindChild(FindGameObjectsWithTag("CheckPoint").ToList();
        //GameObject veicolo = zzzplayer.transform.Find("Veicolo").gameObject;
        //veicolo.SetActive(false);
    }
